I'm a bit leery of the results, as they depend on some negative torsion about 
the pivot for the python. I can't say how the body's real response corresponds 
to K, but it seems that it must to some degree because our bikes are ridable!

It is still first for me. Most people think that Google tracks your searches in 
many ways. If you have cookies on and always use the same IP number, they will 
build a profile of your searches and click-throughs and taylor the results! I 
just read yesterday that they have 2x the ad "relevance" of Yahoo! for that 
reason.

Thanks,
